LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 477,034, dated J' une14, 1892. Application iiled August 19,1891. `Serial No. 403,127. (Nomodel.)

To all whom it may concern;

Beit known that I, FRANK THEoDoEE WIL- LIAMS, of Meriden, in the countyof New Haven and State of Connecticut, have invented a new Improvementin Lamp-Burners; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent a view in side elevation of a lampfount,a burnersocket, and aburner-slip constructed in accordance with myinvention and arranged oneabove the other in the order of their assemblance.

My invention relates to an improvement in central-draft lamp-burners,the object being to produce a simple and cheap burner in which theburner-slip may be disconnected from the burner socket for cleaning theburner without disconnecting the said socket from the lamp-fount.

lVith these ends in view myinvention consists in the combination, withaburner-socket having one or more double-ended bayonetslots formed inits flange, of a burner-slip having one or more simple bayonet-slotsformedin its flange, and whereby the turning of the burner-slip todisconnect it from the burnersocket will turn the same and change oneend of its double-ended slot for the other end thereof with respect tothe retaining nub or point entering the said slot from the lampfount,with which the burner-socket is thus kept coupled.

The burner-slip A is of ordinary construction and has the ordinarybayonet-slot B formed in its iiange, which co-operates with an inwardlyprojecting nnb or retainingpoint B', formed by striking in a portion ofthe flange of the burner-socket C, which is also of the usualconstruction, with the exception that its bayonet-slotD, formed in itslian ge, is double-ended, or, in other Words, extended laterally in bothdirections to form two ends CZ and d. The said double-ended slot Dcooperates with a nub or retaining-point D', formed by striking inward aportion of the flange E of the collar E', permanently attached to thelamp-fount F. Vhen under the above-described construction the burnerslipis turned in the direction of the arrow a to disconnect it from theburner-socket for cleaning the burner, the friction between it and thesaid socket will cause the same to be turned, also, in the samedirection, whereby the end d of its double-ended bayonet-slot is changedfor the end CZ' thereof with respect to the retaining-point D' and thecoupling between the burnersocket and the lampfount maintained, so thatthe said socket will not be removed from the lamp-fount when theburner-slip is lifted to disconnect it from the burner-socket. Vhen theburner-slip is replaced upon the burner-socket and turned in beingconnected therewith, the burnersocket also turns again, whereby the endd' of its double-ended bayonet-slot is changed for the end d thereofwith respect to the retaining-point D', with which the said end d isnormally engaged. It will thus be seen that my improved constructionprovides extremely simple and inexpensive means for constructing aburner with a removable slip, which may be taken oft and replaced atpleasure without disconnecting the burner -socket from the lamp-fount.Although, as shown in the drawings, the burner-socket and burner-slipare each provided with only one slot, they will be ordinarily providedwith two each, the slots of the slip quartering, so to speak, with thoseof the socket.

I am aware that it is not new to couple a burner-slip and aburner-socket together by means of a simple bayonet-lockinvolving thevery objection which it is the purpose of my present invention toavoid-that is, the accidental removal of the 'burner-socket with theburner-slip when it is intended only to remove the latter. Thus it isthat, while heretofore burner-sockets have had simple or oneendedbayonet slots, I provide them with double-ended bayonet-slots, which arethe characteristic and novel feature of my present invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, isl In a lamp-burner, the combination, with a IOOburner-soeket having one or more doubleended bayonet-slots formed in itsange, of a burner-slip having one or more simple bayonet-slots formed inits flange, substantially as set forth, and whereby the turning of theburner-slip to disconnect it from the burnersooket will turn the sameand change one end of its double-ended slot for the other end thereofwith respect to the retaining nnb or 1o point entering the said slotfrom the lampfount, with which the burner-socket is thus coupled.

In testimony whereof I have signed this speeieation in the presence oftwo subscribing witnesses.
